Positions of marks used in racing
Courses use a mixture of special racing marks and navigation buoys. When the courses are announced, racing marks may be identified by their sponsor's name. On the charts their abbreviation is used. Sponsored marks will have the sponsor's name stencilled on them, which may ease identification.
The positions given below are likely to be approximate, especially for the sponsored racing marks, although every effort is made to locate them precisely. Use them as a guide.
St Mawes (Lugo) south Cardinal is listed here, but it is not a mark of any course. However all Sailing Instructions require that boats shall keep to seaward of this mark while racing.
